CHARLES W. DAKE, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE PYLE-NATIONAL COM- PANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.

LOCOMOTIVE LIGHT.

Application filed December 29,1921. Serial No. 525,721.

To all whom it may concern:

Be it known that I, CHARLES W. DAKE, a

citizen of the United States, residing at Chi-.

cago, in the county of Cook and State of Illinois,'have invented a certain new and useful Improvement in Locomotive Lights, of which the following is a specification.

This invention relates to locomotive lights, and particularly to such lights intended to be mounted in the rear. of the locomotive or locomotive tender. One object is .to produce a light which will produce a strong light which will in effect be a minature headlight, and which can be mounted in'the rear of locomotive or tender. Another object is to provide a light which may alternately be used as a headlight and as a warning light. Another object is to provide a light which will throw alternately either a white or colored beam. Another object is to provide a light which will throw a beam along the right of way, and will also throw a beam across the right of way so as to illuminate both the rear of the tender and the right of way to the right and left of the tender. Other objects will appear from time to time throughout the specification and claim.

My invenion is illustrated more or less diagrammatically in the accompanying drawings, wherein Fig. 1 is a vertical cross section;

Fig. 2 is a perspective of the shutter supporting cradle;

Fig. 3 is a cross section on line 3% of Fig. 1;

Fig. 4 is a perspective of the reflector; Fig. 5 is a perspective of the fixed shutter.

Like parts are designated by like characters throughout.

' A is a light housing having brackets A A by means of which it may be attached to any suitable source. It is provided on either side, preferably adjacent the top with two conduit inlets ,A A In the form shown the casing A is open at its bottom as at A and is provided with a glass A. By means of this opening the light is thrown downward as well'as laterally and forward. The rear of the casing A is rounded as at A to provide space for the shutter.

The outward side of the casing is provided with an opening which is preferably circular. This opening is adapted to be closed by a circular door B which is hinged by means of the clamping ring 13". Mounted inside of the lens B and adapted also tobe held in position by the clamping ring B? is-a fixed shutter B which as shown,

in part overlies the lens. I

Mounted within the casing is the socket C within which the light source C is removably mounted. In the rear of the light source is a fixed-reflector C which is permanentlyfastened to the interior of the casing A as shown. This reflector is provided with the rounded portion C Pivoted within the casing is a cradle made up of the shutter supporting ring C' and the arms C C which carry at their outer ends collars C C The collar C has upon it the two lugs C C Adjacent the collar C7 is an annular groove C". Within this groove is mounted a ring C which has on its upper side a 100 C into which one end of the coil spring 12 is fastened. The other end of this spring is fastened to an eye C on the interior of the casing A. The cradle just described is mounted in the casing. by means of the stub shafts C C which are fixed respectively in the collars C C The stub shaft C is pivoted within the projection C on the interior of the housing A. The stub shaft C is mounted for rotation in a similar projection C and extends through the housing. Upon the end of this stub shaft is mounted a thumb nut C by means of which it and the cradle may be rotated so as to move the shutter. Within the supporting ring C is mounted a circular glass shutter C which is made of colored glass of any suitable color. Mounted on either side of the interior of the casing A. and below the cradle are two reflectorsD D. These reflectors are adapted to reflect light laterally through the opening A in the bottom of the casing so as to illuminate the side of the right of way.

Vhile I have shown an operative inven tion, still it will be obvious that many changes in form shape, and relation of parts may be made without departing materially from the spirit of my invention, and I wish therefore that my showing be taken as in a sense diagrammatical.

A? is a lug or projecting member in the casing A which is contacted by one or the other of the lugs C C and thus prevents the frame C from being overthrown passed the proper position when it is rotated either into or out or" operation.

The use and operation of my invention are as follows:

It is customary to have a light at the rear of a locomotive tender. This light is intended generally as a warning. Usually this light is red. Many times, however, locomotives are driven for considerable distances backward and it is then necessary to have a powerful light on the rear of the tender in order to serve as a warning and also to illuminate the right of way both in the direction of travel and laterally. In the arrangement shown the beam will be white, the beam of light being reflected from the fixed reflector, the colored glass shutter being as shown in the rear of the reflector and therefore out of operation.

When it is desired to have a colored beam of light the shutter is rotated by means of the thumb nut and it is swung either up or down or over or under the light source and comes into the position shown in dotted lines, in which it lies across the opening of the casing and directly in the path of the rays of light from the light source. Thus a beam of light passing through a colored glass is colored, and thus at the will of the operator the light may be used either as a colored warning light or as a powerful headlight.

I claim:

In a light, a casing, and a single light source therein said casing having an open bottom and an open front the light from said light source adapted to shine through said open tront, the light being adapted to shine directly through the open bottom'o-f the casing, in combination with a pair of reflectors mounted within said casing, each adapted to reflect a beam of light laterally and downwardly through the open bottom of said casing, in combination witlrai movable shutter having transparent colored glass therein and adapted to be moved into the forward path olsaid light and adjlustably tobe moved behind said first mentioned re= flector out of the pathof said light.
